Ah yes, O-Cha. O-Cha was my first "real" Japanese tea vendor, and it has topped my list of fave Japanese tea vendors ever since, approaching 5 years now. Yutaka Midori has been my fave Japanese tea from my first taste. Back then, there was one and only one Yutaka Midori, it is the original and a credit to the excellent sourcing of Kevin and his Japanese wife, Kaoru. I simply call it (YM) Classic.
Other faves include Miyabi, Sae Midori, Chiran, Fukamushi Supreme, Kabusecha, and Kirameki Shincha. Kame Jiru-Shi is hands down my fave Gyokuro and I like the others as well.
I just today received my first 5 Organics from O-Cha, a new chapter in my enjoyment of O-Cha teas.
Over the years, I would like to think that my recommendations and samples sent of O-Cha teas have led many others to try not only O-Cha tea, but to try "real" Japanese teas for the first time. I make no apologies for my frequent recommendations/endorsements/enjoyment of O-Cha teas.
